IGCSE Accounting: Sources and Recording of Data (Cambridge 0452)

Syllabus edition note. This resource follows the Cambridge IGCSE Accounting 0452 syllabus for exams in 2027, 2028 and 2029 (version 1), first examined in the March 2027 series in India and the June 2027 series elsewhere. If you sit 0452 in November 2026, you sit the 2026 syllabus (version 2), which differs: Paper 1 has 35 multiple-choice marks in 1 hour 15 minutes, not 40 marks in 1 hour 30 minutes; Topic 7 is “Accounting principles and policies”, without 7.2 Ethical considerations or 7.3 Technology and sustainability; 4.4 is “Irrecoverable debts and provision for doubtful debts”; income statements are named instead of statements of profit or loss; three-column running balance accounts are not required; Clubs and societies is 5.4 and Manufacturing accounts 5.5; and 6.3 is “Inter-firm comparison”. For this topic, the 2026 syllabus also asks candidates to complete pro-forma business documents and to explain the advantage of using books of prime entry, and it does not include digital ledger accounts or the benefits and limitations of keeping cash at the business property and of manual and digital original entry. If you sit in November 2026, work from the 2026 syllabus on the Cambridge International website.

This guide covers Topic 2 Sources and recording of data, for Cambridge IGCSE Accounting 0452, syllabus for exams in 2027, 2028 and 2029 (Version 1). Accounting 0452 is not tiered — all candidates study the same content and sit the same two papers.

Where this fits in 0452

Sources and recording of data is the second of seven topics in 0452, and it is where the subject moves from the definitions introduced in Topic 1 — the accounting equation, assets, liabilities and owner’s equity — into the actual mechanics of keeping a set of books. Every later topic assumes this one is secure: verification of accounting records in Topic 3 is entirely about checking that double entry has been applied correctly, and the financial statements prepared in Topic 5 are built directly from the ledger accounts this topic teaches candidates to construct. Get the double entry rules wrong here and errors compound through every later stage of the course. It is also the topic that most closely mirrors what a junior bookkeeper actually does day to day — receiving a document, deciding which book of prime entry it belongs in, and posting it correctly to the ledger — which is why examiners lean so heavily on realistic scenario questions here rather than abstract theory.

Syllabus coverage

CAMBRIDGE IGCSE ACCOUNTING 0452 — TOPIC 2 SOURCES AND RECORDING OF DATA

• 2.1 The double entry system of book-keeping — the double entry system; how to prepare ledger accounts and post transactions to them; how to calculate ledger account balances and make transfers to financial statements; how to interpret ledger accounts and their balances; ledger accounts presented in three-column running balance format; the division of the ledger into the sales ledger, the purchases ledger and the nominal (general) ledger; how ledger accounts can be kept digitally. Candidates do not need to explain or use folio columns.
• 2.2 Business documents — the invoice, debit note, credit note, cheque counterfoil, paying-in slip, receipt, bank statement and statement of account; how these documents are used as sources of information; these documents being produced and recorded manually or digitally.
• 2.3 Books of prime entry — how to process accounting data in the cash book, petty cash book, sales journal, purchases journal, sales returns journal, purchases returns journal and the general journal; how to post the ledger entries from them; trade discount and cash discount and how each is treated; the cash book’s dual function as a book of prime entry and a ledger account for bank and cash; how to record receipts and payments made by cash, cheques, debit and credit cards, online and bank transfers; the purpose of the imprest system of petty cash and how to apply it; the benefits and limitations of keeping cash at the business property; and the benefits and limitations of manual and of digital methods for the original entry of business transactions.

How to approach it

The double entry rule that trips up the most candidates is not the rule itself — debit the receiving account, credit the giving account — but applying it consistently to unfamiliar transactions under exam pressure. Rather than memorising a list of “debit this, credit that” pairs, practise deriving the entry from first principles for a genuine mix of transactions (a cash purchase, a credit sale, a return, an owner’s drawing) until the underlying logic is automatic. The syllabus does not require folio columns, but it does say ledger accounts may be presented in three-column running balance format, so practise both the traditional two-sided account and the running balance layout shown below. For business documents, the syllabus asks how each is used as a source of information rather than for completing documents from scratch — being able to say why a credit note is issued (to correct an overcharge or record returned goods) and how it differs in direction from a debit note is worth more than being able to redraw one from memory. The seven books of prime entry are the section most often confused with the ledger itself: keep the distinction sharp — a book of prime entry is where a transaction is first recorded from a source document, and the ledger is where it ends up after posting — and practise tracing a single transaction all the way from its business document, through the correct book of prime entry, to its final ledger posting, since that end-to-end trace is a common structured-question format on Paper 2. The cash book’s dual role is genuinely unusual among the seven books and worth a dedicated pass of revision: it is simultaneously a book of prime entry for cash and bank transactions and a ledger account in its own right, which is why it does not get posted to a separate ledger account for cash and bank the way the other six books do. Finally, the imprest system for petty cash is a calculation topic in its own right — practise reimbursement calculations (the amount to restore is the total spent, which is the float minus the cash left in the tin) until they are fast and reliable, since these appear as short, mark-scheme-friendly questions that are easy to lose marks on through simple arithmetic slips rather than misunderstanding.

It is worth building one worked example that runs the full cycle for each of the seven books of prime entry, rather than revising each book as an isolated definition. Take a single realistic month of trading — a handful of credit sales and purchases, a few returns in each direction, one or two cash transactions and a petty cash float — and work through which document triggers each entry, which book of prime entry receives it first, and where it is ultimately posted in the ledger. This kind of consolidated practice exposes the errors that isolated drilling tends to hide: forgetting that a sales return is recorded in the sales returns journal rather than reversed directly in the sales journal, or posting a credit note to the wrong side of a customer’s account. Because Paper 2’s structured questions often present a mixed bag of source documents and ask candidates to route each one correctly, this kind of end-to-end rehearsal — rather than book-by-book memorisation — is the single highest-value use of revision time for this topic.

Three-column running balance accounts

A running balance account records the same double entry as a two-sided account, but shows debit, credit and a balance after every entry. A trade receivable, K Lee, owes $300 on 1 March. On 8 March the business sells her goods on credit for $450, on 15 March she pays $500 by bank transfer, and on 20 March she returns goods worth $50.

K Lee account
Date      Details          Debit $   Credit $   Balance $
1 Mar     Balance b/d                               300 Dr
8 Mar     Sales               450                   750 Dr
15 Mar    Bank                          500         250 Dr
20 Mar    Sales returns                  50         200 Dr

The closing balance, $200 Dr, is what K Lee still owes: the same figure a two-sided account would give after balancing. Label every balance Dr or Cr, because a credit balance on a customer’s account (for example, after an overpayment) means the business owes the customer.

Cash, digital records and manual entry

Topic 2 also asks for judgement, not only recording. Receipts and payments can be made by cash, cheque, debit or credit card, online or by bank transfer, and each is recorded in the cash book in the same double entry way.

• The imprest system. The petty cashier starts each period with a fixed float and is reimbursed with the amount spent, as shown by the vouchers, so every period starts with the same float. Its purpose is to control small cash payments: spending is checked against vouchers whenever the float is restored, and the main cash book is kept free of many small entries.
• Keeping cash at the business property. Benefits: cash is on hand for small, immediate payments and for giving change, without a trip to the bank. Limitations: cash can be stolen, lost or miscounted, it needs secure storage and may need insurance, and it earns no interest.
• Manual original entry. Benefits: cheap to start, needs no equipment or software, and is not stopped by a power or system failure. Limitations: slow, open to arithmetic and copying errors, and harder to back up, search and summarise.
• Digital original entry. Benefits: fast, with totals and postings calculated automatically and records that are easy to back up, search and report from; ledger accounts can be kept digitally and business documents produced and stored digitally. Limitations: set-up, equipment and training costs, the risk of system failure or data loss, and an input error is posted everywhere automatically rather than being spotted at the next manual step.
